DEMOUNTALBLE RIM FOR TIRES.

Lineair.

v Specification of Letters Patent.

Application filed January 8., 1913, Serial No. 740,778. Renewed February 7, 1916. Serial No. 76,774.

To all whom t may concern:

Be it known `that I, FOREST J. Cnoor, a citizen of the United States of America, and

resident of Warsaw, Kosciusko county, In-r diana, have invented a certain new and use ful Improvement in Demountable Rims fo Tires, of which the following is a specification.

My invention relatesy to a split 'demountable rim for tires.

It relatesparticularly to such a rim which A is readily attached to and detached from a pneumatic vehicle tire. Insuch constructions it is desirable to employ a rim upon which the tire is mounted, which rim can be readily removed from the wheel of the vehicle, and to then provide means whereby the rim can be readily 'removed -from the tire. My invention accordingly contemplates the employment of a. collapsible rim which can be first removed from the wheel and then collapsed so as to permitthe rim to be removed from the tire.

These and other objects of my invention will be more readily understood by having reference to the accompanying drawings, in which#- l r 1' f Figure 1 is a side elevation of a wheel upon which is mounted a removable rim embcdying the features of my invention. Fig.

2 is a sectional view taken on the line 2-2 ,out of engagement with the tire and the rimv in Fig. 1. Fig. 3 is an enlarged side elevation of a portion of. the rim. Fig. 4 is a b0t;' tom view of-the rim portion lshown in Fig. 3.

As illustrated, my demountable rim comprises al main portion .and two hinged or movable portions 7 and 8. 'Ihis rim is shaped so as to grip the inner edge of the tire 9 and is removably secured to the outer circumference 10 of the wheel by means of a series of clamps 11'. These clamps can be of any desired or suitable form, although I ind that very eiiicient results are obtained by'means of the clamp illustrated which consists essentially of an upwardly extending arm 12 having an inturned end portion 13 which is adapted to engage with .a groove 14 in the side of the rim. These clamps 11 are bolted in locking position by means of the bolts 14. It will be readily seen that by hinged to the main portion 6 atthe pointsy 16 and- 17. These hinged portions 'are adapted to be swung outward so thatthey fit together and form a continuous rim for the Wheel. In'order' to hold the sections together, I provide upon the section 7 a pair of locking members' 18 which engagel with the studs 19 carried by the-member 8. In order to hold theselocking members 18 in engagement with the studs 19, I provide a Patented Mar. 14, 1916.

spring platefZO which is'held upward by a` I small spring pressure 'exerted bythe spring 2l so as to prevent these locking members from moving inward out of vengagement with the. studs 19.

When the rim and tire have been removed vfrom the wheel,'by loosening the clamping members, it is then merely necessary to move this spring plate out of engagement with the locking vmembers 18, at which time these members can be disengaged fromthe studs 19 and the hinged members 7 and 8 then swung downward in the position shown'in dotted lines in Fig.. 1. It will be seen that the portion 6 of the rim can then be lifted readily removed.

While I have illustrated my invention in connection with a particular form of clamping members and with particular locking mechanism, it is understood that I do not wish to limit my invention to su'ch construction, but that other suitable types of clamp? ing or locking mechanisms can be employed, likewise the number of these clamps can be suitably varied. p

What I claim as my invention is:

1. In a demountable rim for tires, a main section, a hinged section pivoted to each end of saidL main section, means for locking said hinged sections together, said means comprising a hooked arm carried by one section and adapted to engage with a stud carried by the other section, and a spring op- ,erated plate for holding said arm in locking other of said sections, anda spring plate for holding said arms in position.

Signed by me at Warsaw, Indiana, this 31 day of December 1912.
